A quick timeline:
DigibronyMLP Era: 2011 - 2014
-Conrad Collins (Digibro) started out as a My Little Pony "analyst" on youtube, going under the name Digibrony. He quickly gained popularity within that community before controversially leaving it to start his "anime analysis" career.
-Met a group of other MLP content creators, which will eventually become the PCP (ProCrastinators Podcast)
Oldschool / Golden Age of Digibro: 2014 - 2017
-Officially transitioned into doing anime content on youtube.
-This era is where he got most of his subs, he had a reputation for going against the grain. Having opinions that were controversial in the anituber community.
-Gained popularity by shitting on crappy anime such as his SAO, Asterisk Wars etc...
-He also produced a lot of vlogs on his Digibro After Dark channel which would garner him a modestly sized patreon (4000$ at its peak in 2018/2019)
-The ProCrastinators Podcast was also officially formed during this period.
Pantsu Party / May Invasion Arc: 2017 - 2020
-Conrad started dating one of his fans (May/Pantsu Party), this was to the dissatisfaction of his fanbase, as Conrad would frequently feature her in his videos. May was a yes-man, and not particularly interesting at all.
-May got Conrad addicted to weed, this noticeably affected his content output and quality. His channel began slowing down in popularity, eventually becoming stagnant.
-Conrad would eventually move to Boston with her in 2018, and change his branding briefly during that period (Otaku Gonzo Journalism) this branding was a failure, and he would eventually go back to just "Digibro".
-During this period, Conrad had planned to start a family with his fiancee May, so he moved back to his hometown of Virginia Beach with her in mid/late 2019.
Troon / Voidgazers Saga: 2020 -
-Conrad trooned out in early 2020, changing his name to "Beatrice". Many speculate that May was the root cause for his mental illness.
-The Digibro channel was rebranded as Diginee (Digibro + onee-san, the word used for older sister in Japanese. Clever right?)
-In mid/late 2020, Conrad would move a bunch of grifters (Vizier, Bird, Mint) into his house. These grifters are somewhat associated with the Dick Show, Vizier being a producer of the show. May did not like these people.
-Conrad broke up with May in late 2020, this was recently revealed to be because May had cheated on him with The Gunt.
-Conrad stopped making anime content during this period
-Conrad and his crew, the "Voidgazers" would make a bunch of shitty travel vlogs and terrible music. This pissed the majority of his fanbase off, who were mostly interested in anime content.
-In early 2021, Conrad privated all of his old videos and completely rebranded his main channel as YGG Studio. At this point most of his fanbase had abandoned him.
